Computer



FIG. 1 is a perspective view of a computer showing my new design.

FIG. 2 is a side view thereof; and,

FIG. 3 is a top view thereof.

In the figures, the broken lines showing the ventilation outlets are included for the purpose of illustrating portions of the computer that form no part of the claimed design. 

I claim the ornamental design for a computer, as shown and described.
